The touch screen is damaged easily? Son, you don't use a knife on it, you use a stylus. I've used mine since launch and the only marks are anything I leave on there when I use my finger on the screen, and easily removed with a tissue.
How you can be underwhelmed with a software library so amazing baffles me. Who cares about the OS? You barely see it because it politely gets out of the way so you can game in peace.
